Hacking Backups stopped working after 4.2 update

[CheesyJedi]

Hey guys, I updated my hacked 3.2u Wii to 4.2 using this guide, and then followed this cios guide to be able to play backups again.
I tried Neogamma, and I can load games fine from USB, so I know that the cios installation worked, but any disk that had worked just fine a day before on 3.2 was now returning a disk read error...
Is there something I'm missing that is required to read burned disks? I have DVDx...
The disks are DVD+Rs, but I burned them with DVD-ROM setting and they worked fine on 3.2 :/
Thanks in advance for the help

Did you update your cios if you did which did you use

Ya, I followed the aforementioned guide, so basically I'm using cios 249 rev 19, and all the hermes cios's (as specified in the guide).
It works when loading through USB...just not disks :/

You should install Darkcorp to play discs from disc channel.

EDIT: Make sure you have priiloader installed.

Out of Region games wont work either from disc channel on 4.2 unless you enable the correct priiloader hack.

Thanks for the replies.
I did install DARKCORP, not that it helped (same error in Neogamma, disk channel gives error and shows question marks around the disk)
The games are the same region as the Wii :/
It's gotta be a software thing because they all worked fine the other day, I just have no idea where to look
